Btw, how does this work on X? When we wait in waitpid for a subprocess launched via "M-!", we are not supposed to call the read-socket hook, so the X messages that tell us to redraw portions of our frames are not supposed to be redrawn. If this is what happens, then the w32 behavior seems to be consistent; if not, what am I missing here? Specifically, can you show a backtrace on X from calls to expose_frame when we are waiting for a synchronous subprocess? TIA
